A Billing Specialist, or Billing Clerk, is responsible for overseeing the billing process for customers or patients. Their duties include processing payments on behalf of a customer or patient, maintaining organized financial records to aid reporting, and calculating bill totals by looking through previous financial statements. Billing specialists typically work for insurance companies or healthcare facilities to maintain accurate financial records and payment procedures. They work closely with customers, patients, or company personnel to create invoices and check for calculation errors on invoices and other billing statements. Their job is to contact customers to remind them of upcoming payment deadlines and help customers find financial aid options to reduce their medical or insurance bills.

Medical assistants provide physician support services that ensure that healthcare facilities run smoothly. They are responsible for administrative as well as clinical tasks, such as maintaining patient records, preparing patients and rooms for examination, assisting physicians with exams, and performing front-desk tasks. Medical assistants typically work in physician's offices, hospitals, and other healthcare facilities. Other duties include recording and updating medical histories and contact information in patient files, scheduling patient appointments, and performing standard care procedures like drawing blood, checking vitals, or collecting lab samples.
